使用当前用户的UID将图像上传到Firebase存储 [英] Upload Image to Firebase Storage with the current users UID

问题描述

您如何上传同时附加了当前用户的UID的图像?

How do you upload an image that will also have the current user's UID attached?

以下示例.

这是我用来上传图片的代码，但到目前为止，添加UID都没有成功.

This is the code I am using to upload the image, but so far having no success adding on the UID.

private void updloadImage(Uri pickedImage){
        StorageReference myStorage = FirebaseStorage.getInstance().getReference().child("users_photos");
        final StorageReference imagePath = myStorage.child(pickedImage.getLastPathSegment());
        userID = fAuth.getCurrentUser().getUid();
        imagePath.putFile(pickedImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                imagePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                    @Override
                    public void onSuccess(Uri uri) {
                        UserProfileChangeRequest myUpdate = new UserProfileChangeRequest.Builder().setPhotoUri(uri).build();


                    }
                });
            }
        });

推荐答案

如果您希望用户的UID成为Cloud Storage中映像文件名的一部分，则可以执行以下操作:

If you want the user's UID to be part of the image file name in Cloud Storage, you'd do:

StorageReference myStorage = FirebaseStorage.getInstance().getReference().child("users_photos");
final StorageReference imagePath = myStorage.child(pickedImage.getLastPathSegment());
userID = fAuth.getCurrentUser().getUid();
imagePath.putFile(userID+"_"+pickedImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {

如果您希望用户的图像基于用户的UID放在子文件夹中，则可以将最后一行更改为:

If you instead want the image(s) for a user to end up in a subfolder based on their UID, you'd change that last line to:

imagePath.child(userID).putFile(pickedImage).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
